One of the best one punch knockout artists ever doesn't just turn into a volume puncher. Doesn't happen.

He never lost power it was just that Goldman changed his style made him shorten his punches but throw more of them in order to break down fighters and ruin them.

I think this fight would play out like most Wlad fights: Wlad constantly throwing jabs, jab, jab, hard jab, right cross, hold and lean and repeat. Of course Wlad would be punching down with all of his weight making his punches land with more authority and against someone who is 60 lbs lighter granite chin or no it's gonna be making an impact. Of course Marciano isn't an easy target he'll be leaning back to the right with his hands crossed over to negate straight punches and would bob and weave and explode up with 2-4 hard punches, most of them would be landing on Wlad's arms, hips and stomach. I think any time Marciano lands a good shot that rocks Wlad he will hold and lean to tire out Marciano and constantly try to spoil. Marciano will fight very galantly but will ultimately lose. Probably. Maybe.
